There are several individual sites or vineyards with this designation:
The single vineyard was already mentioned in a document in 1513. The name refers both to a lime kiln for burning lime that stood here in the 15th century and to the abundant rock found here. The south-facing vineyard at 130 to 150 metres above sea level with a 15% slope covers five hectares of vines. It is bordered to the north by several sandstone walls. The soil is a mixture of lime, loam, marly clay and occasionally limestone rubble. The Riesling variety is cultivated here. The Bassermann-Jordan, Dr. Bürklin-Wolf, Kimich, Siben and Weingut von Winning wineries, for example, have shares in the site. There is another single vineyard in Germany called Kalkofen in the municipality of Bad Dürkheim/Leistadt (also in the Pfalz growing region).
